We study the evolution of US mortgage credit supply during the COVID-19 pandemic. Although the mortgage market experienced a historic boom in 2020, we show there was also a large and sustained increase in intermediation markups that limited the pass-through of low rates to borrowers. Markups...

We use a new methodology to assess mortgage pricing discrimination by race. We make four main contributions. First, we show that existing estimates of mortgage pricing differences by race can be confounded by a "menu problem," which is the problem associated with evaluating equality in...

The COVID-19 pandemic exacerbated racial disparities in U.S. mortgage markets. Black, Hispanic, and Asian borrowers were significantly more likely than white borrowers to miss payments due to financial distress, and significantly less likely to refinance to take advantage of the large decline in...

This paper develops and estimates an instrumental variables strategy for identifying the causal effect of securitization on the incidence of mortgage modification and foreclosure based on the early payment default analysis performed by Piskorski, Seru, and Vig (2010). Estimation results show...

We estimate a model of foreclosure using a data set that includes every residential mortgage, purchase-and-sale, and foreclosure transaction in Massachusetts from 1989 to 2008. We address the identification issues related to the estimation of the effects of house prices on residential...

We evaluate the effects of laws designed to protect borrowers from foreclosure. We find that these laws delay but do not prevent foreclosures. We first compare states that require lenders to seek judicial permission to foreclose with states that do not. Borrowers in judicial states are no more...

Surprisingly little is known about the importance of mortgage payment size for default, as efforts to measure the treatment effect of rate increases or loan modifications are confounded by borrower selection. We study a sample of hybrid adjustable-rate mortgages that have experienced substantial...

While mortgage rates reached historic lows during 2012, the spread between primary and secondary rates rose to very high levels. This trend reflected a number of factors that potentially affected mortgage originator costs and profits and restrained the pass-through from lower secondary rates to...

Using new household level data, we quantitatively assess the roles that (i) job loss, (ii) negative equity, and (iii) wealth (including unsecured debt, liquid, and illiquid assets) play in default decisions. In sharp contrast to prior studies that proxy for individual unemployment status using...

This paper explores the question of whether market participants could have or should have anticipated the large increase in foreclosures that occurred in 2007 and 2008. Most of these foreclosures stemmed from loans originated in 2005 and 2006, leading many to suspect that lenders originated a...
